摘要：Abstract – Increasing demand for cloud applications has led to an ever growing need for security mechanisms. Cloud computing is a technique to leverage on distributed computing resources one do not own using internet facility in pay per use strategy on demand. A user can access cloud services as a utility service and begin to use them almost instantly. These features that make cloud computing so flexible with the fact that services are accessible any where any time lead to several potential risks. The most serious concerns are the possibility of lack of confidentiality, integrity and authentication among the cloud users and service providers. The key intent of this research work is to investigate the existing security schemes and to ensure data confidentiality, integrity and authentication. In our model symmetric and asymmetric cryptographic algorithms are adopted for the optimization of data security in cloud computing.
